Chapter 71: Inference as Categorical Necessity
The inference rules of τ are not conventional stipulations, nor are they revelations from a Platonic realm of logical truths. They are structural necessities: consequences of the kernel’s architecture that any system built on five generators and seven axioms must exhibit. Modus ponens is morphism composition. Conjunction introduction is product formation. Existential quantification is the left adjoint to pullback along a projection. Each rule is earned from the topos-internal logic of τ, not imposed upon it. The classical debate between conventionalism and logical realism dissolves: inference rules are neither arbitrary choices nor pre-existing eternal truths but structural features of any category with τ’s compositional architecture.
